Aspectrics, Inc., a leading supplier of Encoded Photometric Infrared Spectroscopy (EP-IR) analyzers, recently received its fifth U.S. patent for its Encoded Photometric Infrared Spectroscopy disk technology and associated optics. The new patent number 6,982,788 was filed May 29, 2000, and issued Jan. 3, 2006.
This patent further strengthens Aspectrics EP-IR encoded disk technology and will allow Aspectrics to develop and deliver new EP-IR products to the marketplace in a more timely manner, said Paul H. Salsgiver Jr., CEO of Aspectrics, Inc.
Aspectrics continues to file additional patent applications covering its fundamental technology to cover recent improvements and variations on the various systems; additional markets where the company may most effectively leverage its technology; and those features most often requested by its customers. The company has dozens of patent applications currently pending and will bolster its portfolio with further filings, from its intellectual property counsel Fenwick & West.
Aspectrics EP-IR technology enables real-time, parts-per-billion monitoring of dozens of chemical components under hostile environmental conditions commonly found in industrial processes. Applications under development by Aspectrics OEM customers using its EP-IR technology include ambient air and stack gas monitoring, engine emission analysis, foods and semiconductor processes.
At the heart of Aspectrics EP-IR analyzer is a rotating disc onto which up to 256 concentric encoding tracks are used to encode dispersed radiation, which is then collected and imaged onto a single-channel detector (as pictured above). The compact design enables very precise intensity measurements under hostile environmental conditions, which enables EP-IR to replace conventional analyzer technologies such as NDIR and FTIR currently used in many process monitoring and control applications.
Aspectrics EP-IR technology was pioneered by founder and CTO, Thomas W. Hagler, Ph.D. For more information on EP-IR, click here.
